Of course, I could be wrong about this. There is a chance that is not the original hose, but I have seen bunches of these with those exact letters and lines reproduced on them. So I only assumed it was the original hose....also because almost every other part on this car was original as well. Maybe a year to year difference from 71-72? I believe the part number on that hose starts with the 20 in the last picture, but is cut off.
Before you go ahead with the fuel line I believe they are already available from most of the restoration suppiliers as well as the tubing suppliers like Classic Tube. I know the Stage-1 line was available which requires the Stage-1 fuel pump but all 455's should run this pump anyway.
The pump to carb line is different on 72 455 A body cars IF the car has A.I.R. aka, smog pump. The large aluminum mounting bracket will not allow the standard line to clear. Smog pumps and EGR valves came on California emissions cars and I believe all 455's with manual transmissions. California emissions cars also got a different carb.
Some did not have them....I don't know what the protocol was on that, though. A good way to tell, is the intake - if it has the cast AIR runners on either side of the intake or not.. I see most of them without pumps now, because people seem to think they need to be trashed.
OK, this in interesting. I was just looking through the production totals book I have, they have three things of interest listed. Total GS production for 72 (hard and ragtop) is 8575 1) 2515 had the "Air Injector Reactor" E2, which would be the AIR system. 2) 969 had the "Exhaust Gas Recirculator" E3 3) 453 had the "Exhaust Emission System" E5, which was calif only I think. Those are mostly 455 machines. The number for the 350s is 728, 728, and 332. Interesting on the first two numbers, the breakdown for the vert and hardtops is identical. So perhaps a typo by Buick or the 350's that got the AIR also got the EGR. There were probably certain states that required certain systems. Even today with the super clean engines, some states still extra equipment for that little bit more or whatever (calif of course but others as well). So the majority of the GS cars did not have these systems it would appear.
TimR, Only the California 350 cars got the smog equipment, and they did get both the AIR system and the EGR's. (This would have been for the cars built for California end users, and not cars built in Calif for delivery to other states.) Duane
Tim, Where did you find these production numbers? Any numbers for power bucket seat, N-25, or SunCoupes other than Skylark 350 SunCoupes? Steve
Thanks Duane, so that answers that but begs the question how did they pick who got what for the rest of the cars?? ou: Steve, Mike Trom on the board here sells the book, he collected the info and put it together, neat little piece. Person needs to remember its only as good as GM documented it. 72 GS N25 was 1538 hardtops and 193 verts. Pwr seat depends on buckets vs bench, and also a lot of these options broke down into groups but many did not so although you know the total you don't know exactly how it worked out (ie for my vert of 852 total built 131 were flame orange but there is no breakdown for stage 1, 455, or 350 cars so all you can do is guess by percentages-and thats all it is, a guess). I don't see any suncoupe info. Well worth buying the book from Mike.
Steve I got my hoses off the Suncoupe yesterday , white stamp no yellow stripe . I need a set of the hoses . PM me with the total shipped to 63116
hey tim what was the exhaust emissions system? E5....was that the coil spring flap that closed off one of the exhaust manifolds to heat up the car quicker?
